Introduction to Java

Java is an object-oriented, high-level programming language originally introduced in 1995 by Sun Microsystems. It was later acquired by Oracle Corporation, which continues to keep it up-to-date. The core portability of Java can be summarized as “Write Once, Run Anywhere” (WORA). This means that after creating a Java program, you can use it on any machine with support for Java, no changes required. That’s one of the reasons why most of the students want to join a Java Course in Pune to make a good base for programming.

Why is Java So Popular?

Key Features of Java
Simple and Easy to Learn
Java’s syntax is very well written and easy to follow, even for a beginner who has never programmed in his life! It gets rid of advanced stuff like pointers in other languages, such as C++. Therefore, students joining Java Classes in Pune find it easier to understand programming techniques in order.

Object-Oriented
Key concepts in the Java language are based on OOP, such as Encapsulation, Inheritance, Polymorphism, and Abstraction. These ideas are intended to assist in making code reusable and modular for developers. An organised Java Class in Pune would always dwell on OOP since it is the foundation behind any development based on Java.

Platform Independent
The executable form of Java programs is compiled for the JVM bytecode. That's what makes it possible for Windows, Mac, or Linux to run Java applications without modification. In Professional Java Training in Pune student understand how the JVM is responsible for making the platform independent.

Secure

Memory management and exceptions are powerful features of Java. These functions decrease the risk of system crashes and enhance reliability. A professional Java Course in Pune helps students to apply the concepts when handling errors and exceptions.

How Java Works
To understand Java, you must know three key things:
JDK (Java Development Kit) – This is used to create Java apps
JRE (Java Runtime Environment) – To execute Java applications
JVM – Runs the Java bytecode
When you develop a program using Java, the compiler compiles it into bytecode. It's the responsibility of the JVM to translate the bytecode into machine code. In advanced Java training in pune trainer mostly explains this internal process at runtime.
Fundamental Structure of a Java Program
Here's a simple Java program to demonstrate this:
public class HelloWorld {


public static void main(String [] arg) {


System. out. println("Hello, World!" );


}


}
Let’s break it down:
public class HelloWorld{ 2. 2 The Class Definition public class HelloWorld is the name of the class that you are defining.
The entry point of the program is main().
System. out. println() writes output on the screen.
